Distributed Load & Infrastructure Stress Testing
Top-tier performance testing company: As a performance testing company, we simulate tens of thousands of concurrent connections against your real infrastructure — surfacing database deadlocks, connection pool exhaustion, and API latency spikes before a product launch or sales event does it in production.
What's Included in Our Scope
- Load testing simulating expected standard user volume to audit average latency and system resource bounds.
- Stress testing pushing applications past their breaking points to observe failover recovery logs and graceful degradation.
- Soak testing running sustained moderate load over 12-48 hours to flag slow memory leaks and database connection exhaustion.
- Spike testing simulating instantaneous traffic surges (e.g., a viral tweet or flash sale) to validate auto-scaling group responsiveness.
- Concurrency sweeps checking database row lock limits, connection pool exhaustions, and API rate limiting gates.
- Third-party API simulation to ensure external gateways (like Stripe or Twilio) don't become the bottleneck.

Frequently Asked Questions
What is the main difference between load testing and stress testing?
Load testing validates if your system performs well under expected, standard traffic levels (e.g., normal daily users). Stress testing pushes the load to extreme, unrealistic limits to see exactly how and where the server breaks, verifying if it handles system limits gracefully without database corruption.
Do we need a production-scale staging environment for accurate results?
Ideally, yes. Testing against a staging environment that is an exact 1:1 replica of production yields the most accurate results. However, if cost is an issue, we can test against a scaled-down environment and mathematically extrapolate the performance limits.
Can you load test applications behind a firewall?
Yes. We can deploy our load generation pods directly inside your private VPC/Kubernetes cluster, bypassing the external firewall to test internal microservice-to-microservice communication and database throughput directly.
